*These items are provided for general information only. They are approximate values and are not 

considered part of a product specification.

Typical Uses

Adcote 49-222 plus Coreactant F is recommended for use in laminations requiring high degrees of bond 

strength, age stability, thermal resistance and chemical resistance. Where ultraviolet resistance is of prime 

concern, Adcote 49-222 plus Coreactant 9H1H would be preferred.

Some typical laminations using Adcote 49-222 are:

- Polyester Film/Polyester Film

- Polyester Film/Metallized Polyester Film

- Polyester Film/Treated Polyolefin Films

- Polyester Film/Polyvinyl Chloride Films*

- Polyester Film/Aluminum Foil

- Aluminum Foil/Treated Polyolefin Films

- Aluminum Foil/Polyvinyl Chloride Film*

Caution

Laminations containing plasticized PVC films should be evaluated thoroughly to determine the resistance of 

the adhesive to plasticizer migration.

Mixing for Use

Adcote 49-222 should be mechanically agitated in the drum prior to catalyzing or diluting. Combine 100 

parts of Adcote 49-222 with 5.5 parts Coreactant F or 4.4 parts Coreactant 9H1H just prior to use. Dilute as 

desired with the desired urethane grade solvents and mix thoroughly.

PACKAGING AND

CONVERTING
Adcote 49-222 November 2010 Page 2 of 2

High molecular weight polyesters that are used in solution adhesives like Adcote 49-222 have a tendency to 

form a reversible structure in solution with time. This structuring is accelerated when the adhesive is 

exposed to temperatures below 50°F. The structuring is reversible if heat and shear is applied to the 

adhesive. We recommend placing he container of adhesive in a steam cabinet, allowing venting of the 

container and heating to 110-140°F. After the adhesive reaches the proper temperature, mix the adhesive 

in the container for 1-3 hours under moderate shear. Use of a disperser or “Cowles” type blade will shorten 

the time needed.

Caution must be taken because of the flammability of the solvents used in the adhesive. Please 

review MSDS for hazards associated with the adhesive.

Attempting to redisperse without heat may reduce the apparent viscosity, but not result in a homogeneous 

mix. Before using the adhesive, check to make sure that all resin has returned to a true solution and no gels 

remain.

Laminating Combining

Laminate to the second substrate using heated pressure-nip rollers at a temperature high enough to assure 

complete wetting of the secondary substrate. A minimum temperature of 70°C (150°F) is recommended; 

however, temperatures approaching 176°C (350°F) may be required to obtain optimum adhesive 

performance in laminations of heavy gauge substrate or where adhesion is of prime importance.

Bond immediately off the laminator is fair. Maximum thermal and chemical properties will develop within 

7 - 14 days. For high performance applications post curing at elevated temperatures of 48° - 66°C 

(100° - 150°F) is recommended.

Safety, Handling and Storage

 Store in cool, dry, well ventilated area away from heat and ignition sources. Keep container tightly 

closed.

 Hot organic chemical vapors can suddenly and without warning combust when mixed with air. 

Ignition can occur at typical elevated temperature process conditions. Please evaluate such 

processes to assure safe handling conditions.

 Support and ground containers before opening, dispensing, mixing, pouring or emptying. Open with 

non-sparking tools. If container is warm, open bung slowly to release the internal pressure.

 Wash thoroughly after handling. Wash contaminated goggles, face shield, and gloves. 

Professionally launder contaminated clothing before re-use.

 ATTENTION! Container can be hazardous when empty. Follow label warnings even after container 

is empty. Do not use heat, sparks, open flames, torches or cigarettes on or near empty containers. 

Do not reuse empty container without professional cleaning.

 Refer to Material Safety Data Sheet for more information.
